Human Protein Wnt-2b (WNT2B) ELISA Kit

WNT2B encodes a member of the wingless-type MMTV integration site (WNT) family of highly conserved, secreted signaling factors. WNT family members function in a variety of developmental processes including regulation of cell growth and differentiation and are characterized by a WNT-core domain. This gene may play a role in human development as well as human carcinogenesis. This gene produces two alternative transcript variants.WNT13 encodes a 372-amino acid polypeptide including a putative secretory signal peptide. Northern blot analysis revealed that WNT13 was expressed as a 2.5-kb mRNA in fetal brain, lung, and kidney. Unlike most other WNTs, which tend to have restricted expression in adult tissues, its transcript was found in a wide variety of adult tissues.

Human Protein Wnt-2b (WNT2B) ELISA Kit has high sensitivity and excellent specificity for detection of Human WNT2B. No significant cross-reactivity or interference between Human WNT2B and analogues was observed.

This Human Protein Wnt-2b (WNT2B) ELISA Kit employs a two-site sandwich ELISA to quantitate WNT2B in samples. An antibody specific for WNT2B has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyWNT2B present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for WNT2B is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of WNT2B bound in the initial step. The color development is stopped and the intensity of the color is measured.

• Do not mix components from different kit lots or use reagents beyond the kit expiration date.• Allow all reagents to warm to room temperature for at least 30 minutes before opening.• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.• It is recommended that all samples and standards be assayed in duplicate or triplicate.
